Explanation:
Secure Socket Tunneling Protocol (SSTP) is a form of VPN tunnel that provides a mechanism to transport
PPP or L2TP traffic through an SSL 3.0 channel. SSL provides transport-level security with keynegotiation, encryption and traffic integrity checking. The use of SSL over TCP port 443 allows SSTP to
pass through virtually all firewalls and proxy servers except for authenticated web proxies.
